Filter by:The aim of this study is to assess the effect of the newly introduced (hybrid dental ceramic) superstructure materials, Vita Enamic versus IPS Emax on implant stability, patient satisfaction and crestal bone loss.
This study evaluates the success rate, as the biological and prosthesis complications, of posterior single-unit implants immediately loaded with a chair side Computer-Aided Design and Manufacturing (CAD-CAM) composite crown, after a follow-up period of 6 months,1,2,3,4 and 5 years. Complementary ex vivo analyses will be performed to evaluate the wear of restorations. The time and cost benefit of the presented digital workflow, as patient centered outcomes will also be evaluated.
This is an experimental study, prospective, comparative. This clinical trial is randomized and double-blind, Residronate versus placebo. The study aims to demonstrate the effectiveness of risedronate in pain management, after 18 month of traitment, in patients undergoing aseptic joint prosthesis loosening. 2 groups were compared with a 1: 1 ratio. The first group receives active drug (risedronate 75mg) and the second a placebo. Patients are treated during 18 months: 1 tablet residronate/placebo per os two consecutive days each month. Evaluations are planned evry 6 months.
Subjects are being asked to participate in this study because they have an arm or leg amputation and have developed pain related to a neuroma (an ongoing localized pain related to a cut nerve ending). The investigators are studying how targeted reinnervation (TR) helps to both treat neuroma pain and to have increased prosthetic control. This surgery connects these cut nerve endings to nerves going into nearby nonfunctional muscles. This surgery was developed to allow amputees to have better prosthesis control. By chance, neuroma pain improved significantly with TR. The investigators, therefore, are conducting this clinical trial. The investigators will ask all participants to fill out a questionnaire both before and after surgery. This will help us understand how a neuroma affects the quality of life of amputee will allow us to understand how to best improve neuroma pain and prosthesis control. In order to confirm the presence and location of the neuroma before surgery, a magnetic resonance image (MRI) will be performed. Taking these pictures requires subjects to lie still for a short period of time but does not involve any invasive procedures.
This phase II clinical trial was designed to assess the feasibility, safety, toxicity, recurrence and survival pattern when TP or CAP chemotherapy was combined with adjuvant radiation for patients with high-risk endometrial cancer.
The purpose of this research study is to identify reasons that cause an all-ceramic bridge to fracture which include the thickness of the bridge material, the type of bridge material and the bite force of the person. This all-ceramic bridge will be compared to a metal-ceramic bridge. The investigators are conducting this study so we can make bridges which can withstand forces in the mouth which tend to break them. The overall objective of this research is to analyze how properties of ceramic materials and different forces in the mouth interact with each other to affect the longevity of these bridges. These include fracture toughness, elastic modulus of ceramic layers and supporting substrate, core thickness, connector height, wear, loading orientation, and maximum clenching force.
The purpose of this study is to compare three different core build-up materials for dental use. The study hypothesis is that there is no differences in survival rate of the different core build-ups.
Clinical evaluation of 4 different bearings in THA. Primary parameter being prosthetic survival data.
